Specification of Letters Patent. Patented une 28., 1921.

Application tiled February 26, 1920. Serial No. 361,383.

To all alma may cof/cern Be it known that I, SAMUEL SLISHMAN, a citizen el* he United States, residing at Chelsea, county of Suffolk, Commonwealth ol lvlaesachusetts, have invented, certain new .and useful improvements in Gasolene- Tanks, of which the following isa specification.

y This invention relates to 'gasolene tanks for automobiles and the like, and particularly to an auxiliary or reserve tank adapted to contain a supply of fuel which may be drawn upon when the supp-ly of Vthe main tanlr has been exhausted.

My invention is designed to avoid the annoyance oi' a failure of fuel supply at an inopportuno time, and to this end the reserve tank is so related to the main supply tenir that the contents of the reserve tan: may be emptied into the main tank by 'the :Sample manipulation of a valve accessibly positioned within the reach of the driver 'Whenever the sup-ply in the main tank has become exhausted, and whereby moreover the reserve tank when emptied ma be con veniently reiilledby and during tl e act el refilling the main tank. By this construetion the driver is assured at all times oil a reasonable emergency supply ol tuali should the main supply tank be emptied, and hisd'ependency upon the usual fuel g e, which frequently fails to satisfactorily in( 'cate the normal luel supply, is thereby lessened.

The construction and o eration of my de vice, together with a preterred embodiment illustrative oi the principles involved, is

` described land shown in the accompany@ spondingl Figure fuel supply tank equipped with my reservel of an automobile or other motor pro ingl specification and drawings, throughout which lilre reference' characters are correemployed, and in the drawings; is a vertical section through a tank an showing the control valve closed.

to prevent delivery of the' contents of the,l

' the main tank 1.

reserve tank.

Fig. lll' an enlarged detail showing the valve o en to permit such delivery, and o Fig.l II is a partialy plan illustrating 1n full and dotted lines the open and closed positions of the valve manipulatm handle. I have indicated at 1 the main el tpinl vehicle. The tank 1' is of conventions, type and is adapted to contain within'aiteelf myl improved reserve tank .2 which ma .ne read` ilyapplied tothe main tank wit out subvcompartment 5 formed b ,stantial modification or reorganization of structure. The illn o ening for the tank 1l is indicated at 3 an t e feed pipe for delivering the fuel to the carburetor is indicated at A. f Y

'My reserve tank is snugly fitted Within a vertical Apartiu tions 6 lixed in spaced re ation Within the tank 1 and has preferably the approximately elbow shape illustrated in Fig. l. The several compartments formed by said partitions are in constant communication With each other as by the ports 61 in said partitions, and the relation of the reserve tank 2 to the main tank l is such that the reserve .tank when empty will be filled by and in the operation of tiling the main tank.

rlhe delivery of fuel content. of the re serve tank 2 into the main 1 and thence lthrough the feed pipe l to the carburetor tially the level of the bottom Wall ot tank.

The stem 12 oi' the valve 'l' may be shouldered as indicated at 13, and a coil spring il :may be conined between said shoulder and a screvv cap 15 threaded onto a nipple 16 surmoimting the guide 9 and normally eiective to maintain the valve 7 in the closed position shownin Fi l, wherein the valve prevents ingress oi te fuel with the guide 9 from the reserve tank 2 and egress from said: guide through the port 10 into Beyond the cap 15 the stem 12 may be extendedand bent over as an operating handle Orcrank 17 which may be carried to'a conveniently accessible, oint adjacent the drivers seat for manip ation bythe driver to open and close thefvalve. Said crank 17 is' adapted to swing over a cam surface :18 in the opening Vmovement of the valve whereby to raise the valve 7 from its seat and when the valve is .'ully open to lodge in al locking recess 19 formed in said cam p surface atl-the upper end of theincline (see mounted Fi II).

gVhen itis 4desired to draw upon the re` serve tank, the driver swings 'the valve handle17 through a art circle to raise the valve 7 to the position shown'in Fig. II, wherein the ports 11 are uncovered and the port 10 isopened to the main tankil so that the contents "of the tank 2 may pass into the tank 1 and thence through the feed pipe A to the carbureter lof the engine.

For convenience of iillin the tank 2 while the main tank 1 isbeing lled thro-ugh the filling openig, one or more filling openings are formed in the tank 2 at any desired level therein. These openings may be provided :with relatively short pipe sections 20 to prevent the admitted fuel from splashing out in the' motion of the car, and near the top of the reserve tank air inlet openings 21 may be provided to assist the automatic filling action. During the filling, the valve 7 may be opened, if desired, to expedite the operation.

The location and relation of the ports 10 and l1 is such thatl both are simultaneously closed or opened by the movement of the valve 7 toward and from its seat 8. The valve itself may be readily removed for cleaning or other purpose by unscrewing the cap 15 while the cam surface 18 and automatic locking engagement of the valve handle 1 7 in thenotch 19 insures not only a full and positive opening of the valve upon operation of the. valve handle 17, but relieves the driver of the necessity of an further attention tothe interchange of el from reserve tank 2 to main tank 1. f

Various modifications in the form and construction of" my device may obviously be resorted to, all without 'departing from the spirit o-f my invention if within the limits of the appended claims.

What I therefore-claim and desire to secure by Letters Patent is:

1. In a liquid fuel tank, a main tank, an auxilia tank having an intake in communicatlon with said main tank whereby filling the main tan-k fills the auxiliary tank, a tubular valve seat extension fixed within said auxilia tank-and having a valve seat,
